To all whom it may'concernv: i I

Be it known that l, MATTHEW MAns'nAnL, S12, a subject of the King of Great Britain, and a resident of Port Coquitlam'; in the. Canada, have invented certain new and useful Improve inents in Coke-Producing and By-Product- Recovery Methods, of which the following is a specification. i

My invention relates to improvements in methods for producing coke and recovering byproducts from the coalat the same time, and the object of my invention isto devisef a method whereby all the available products from. the volatile constituents of without reducing the coal may be recovered the quality of the the quantity or impairing coke produced.

l'n n1 United States Patent No.1,'227,060, dated May 22, 1917, I have shown and described fully a'coking oven suitable for the carrying out of my method, but for the better understanding of this present specification 1 annex a figure showing a cross sectlonalelevation of the oven, to WllLCll reference is made and iniwhich 2 represents the fire brick lined dome structure of the walls and roof, 3 a closablelaperture in the crown through which the oven is charged with coal, and 4-. the uptake flue aperture. The side door opening through which the coke charge is withdrawn is not shown.

5 indicates the sub-fioor sloping conically to the central well aperture 6, which aperture is covered by a grating 7 and from which a pipe 8 closable by a stopcock leads to the condensers in which the by-products arerecovered. 9 indicates the gravel orrock with which the conical space within the subfloor is filled on the upper surface of which fire-brick tiles 10, are laid in parallel rows with an intcrspace 11' between each row of tiles while along the side edges (if-these tiles bricks 13 beingwithout checks.

and also along the middle of eaehrow are placed firebrieks 12 and 13 respectively, the firebricks 12 being checked on their upper sides to form channels, the middlerows-of Resting on the upper sides of thefirebricks 12 are firebricks 14c and resting on each middle row of bricltsli-B is a row of bricks 15, the middle of each side of which for a depth of about two inches is checked so as to form interspaces 16 between them and the bricks 1t 1 Specification of Letters Patent.

and therebeneath these bricltsare beveled inward to where they seat upon the bricks 13, from which it will be seen that the bricks form the floor of the oven, which 14 and 1,5

floor is provided with interspaces 16 through whlcli the volatile matter from the coal be-- ing"coked may pass freely into the channels Patented nee. erect;

The. heat from the upper charge is thus drawn downward and the volatile matter leased by the heat, passes downwardly through the fir'ebricl; door and tiles of the ovenin separate streams and then through strata Or. the through it the oven is charged through the from the coal, re-

I being closed. The charge i being kindled'the draft is first taken through the uptake flue the gravel to the pipe 8 whereby all the available by-products of the coal are re'cov-- cred while at the same time the maximum quantity of coke is obtained and of an improved quality. I

What I claim as my invention is The method of producing coke and re covering the lay-products thereof consisting in inducing a downward draft through a heated charge of coal whereby the heat from the'upper strata of the charge is drawn down ward throu h it and the volatile constituents are given 0 then passing such constituents downwardly in separate streams and then througha finely divided material to the condensers.
